The model combines modern engineering, proven durability, and compliance with strict EPA emissions standards. In the US, Kia Sportage IV specs are especially relevant for used-car buyers, where all-wheel-drive gasoline versions remain the most common. This article dives deep into 2017–2021 Kia Sportage engines, transmissions, dimensions, and key specs based on North American market data. Exterior design, interior features, trim levels, and common issues are covered in other articles in this series.
Engines and Transmissions
The fourth-generation Kia Sportage was offered with a focused lineup of gasoline engines tailored to American driving preferences. All engines meet EPA Tier 3 standards and deliver a strong balance of performance and efficiency. Below is a table of the main powertrains available in the US from 2017–2021.
| Engine | Type | Displacement | Horsepower | Transmission | Drivetrain |
|---|---|---|---|---|---|
| 2.4 GDI | Gasoline, naturally aspirated | 2.4L | 181 hp | 6-speed automatic | FWD, AWD |
| 2.0 T-GDI | Gasoline, turbocharged | 2.0L | 240–245 hp | 6-speed automatic (2017–2019), 8-speed automatic (2020–2021) | AWD only |
The base 2.4L GDI four-cylinder provides smooth everyday performance (0-60 mph in about 9 seconds), while the turbocharged 2.0L (available on SX Turbo trims) offers spirited acceleration (around 7 seconds to 60 mph). All models use a 6-speed or 8-speed automatic transmission. All-wheel drive (AWD) features a dynamically controlled coupling that sends power to the rear wheels when needed and is available on most trims.
Dimensions and Weight
The Kia Sportage IV is built on a platform that delivers compact exterior dimensions with surprisingly spacious interior room. Specs vary slightly by engine and drivetrain.
| Parameter | Value |
|---|---|
| Length | 176.4 in |
| Width | 73.0 in |
| Height | 64.8–65.2 in |
| Wheelbase | 105.1 in |
| Ground clearance | 6.4–6.8 in |
| Curb weight | 3,305–3,765 lbs |
| Gross vehicle weight | 4,740–4,960 lbs |
| Cargo volume | 30.7–60.1 cu ft |
| Transmission | 6-speed auto, 8-speed auto |
| Drivetrain | FWD, AWD |
Curb weight is lower for FWD models and higher with AWD and the turbo engine. The 6.8-inch ground clearance (AWD models) handles light snow and gravel roads well, making the Sportage a solid choice for varied American driving conditions. Cargo space behind the rear seats is a generous 30.7 cubic feet, expanding to 60.1 cu ft with seats folded.
Updates by Year
The 2018 facelift and subsequent annual refreshes brought meaningful improvements to the US-market Sportage:
- Engines: The turbo 2.0L gained slight power bumps and improved low-end response. The 2.4L received minor efficiency tweaks.
- Transmissions: Starting in 2020, the turbo models switched to a smoother 8-speed automatic for better highway fuel economy and refinement.
- AWD system: Enhanced software improved traction response on slippery surfaces—helpful for winter driving in northern states.
- Chassis: Additional sound insulation and retuned suspension improved ride comfort and cabin quietness.
Post-2020 models with the 8-speed automatic are generally considered the most refined and are highly sought after on the used market.
Ownership Notes: What US Buyers Should Know
When shopping for a used Kia Sportage IV, several technical points influence long-term reliability and cost of ownership:
- Engine reliability: The 2.4L GDI is known for durability, often exceeding 200,000 miles with regular maintenance. The 2.0L turbo requires premium unleaded fuel and timely oil changes; turbo components typically last beyond 150,000 miles.
- Fuel economy: 2.4L models achieve 21–23 mpg city / 25–30 mpg highway (FWD). Turbo AWD versions return around 19–20 mpg city / 23–26 mpg highway. Real-world figures depend on driving style and conditions.
- Transmission: Both 6-speed and 8-speed automatics are robust when fluid is changed every 60,000 miles.
- AWD system: The coupling is durable for normal use; avoid prolonged off-road stress to prevent overheating.
- Suspension: Front struts and rear bushings typically last 80,000–100,000 miles on average US roads.
- Parts availability: Parts are widely available through Kia dealers and aftermarket suppliers. Routine service costs are competitive in the segment.
On the used market, AWD models with the 2.4L engine remain the most common and retain strong resale value.
Best Choice for the US Market
Considering American fuel prices, road conditions, and resale trends, the sweet spot for a 2017–2021 Kia Sportage is a post-2020 model with the 2.4L engine, AWD, and higher trims (EX or SX). Reasons include:
- Efficiency & power balance: Solid real-world mpg with adequate performance for highway merging and passing.
- Capability: AWD provides confidence in rain and light snow without major fuel penalty.
- Features & comfort: Higher trims offer desirable tech and safety equipment.
- Value: Approximate market price for well-maintained examples in the United States: $18,000–$25,000 (as of late 2025).
For budget-focused urban buyers, a front-wheel-drive 2.4L in LX or S trim delivers excellent reliability and lower insurance costs.
The 2017–2021 Kia Sportage proves itself as a versatile, dependable compact SUV that continues to deliver strong value on the used market. Opting for a well-equipped AWD model gives you the ideal mix of practicality, comfort, and year-round confidence.
